Description

The present invention relates to a solid fragrance-containing agent for scenting which comprises a carrier and a fragrance. The fragrance is in encapsulated form. The carrier is selected from sugars, sugar alcohols and mixtures thereof. Furthermore, the invention relates to the use of a means for fragrancing objects, in particular textile fabrics, and to methods for producing the means.

In the use of detergents and cleaners, the consumer not only aims to wash, cleanse or care for the objects to be treated, but also desires that the treated objects, e.g. Textiles, after the treatment, for example after the wash, smell pleasant. For this reason in particular, most commercially available detergents and cleaners contain fragrances. Most of the fragrances, however, are volatile. For this reason, when using conventional washing or cleaning agents after use, especially after washing, only a small proportion of the fragrance used remains on the treated object. As a result, often only a faint scent of the treated object, especially the laundry, goes out, which then already weaker after a short time. Thus, the pleasant feeling of freshness of the treated object disappears after a short time.

Often fragrances are used in the form of perfume particles either as an integral part of a washing or cleaning agent, or dosed directly into the washing drum at the beginning of a wash cycle in a separate form. In this way, the consumer can control the fragrance of the laundry to be washed by individual dosage.

The main constituent of such fragrance pastilles known in the prior art is a water-soluble or at least water-dispersible carrier polymer which serves as a vehicle for the integrated fragrances and which dissolves more or less completely in the wash liquor in the course of the waxing process, thus the fragrances contained and possibly to release further components in the wash liquor. In most cases, such a carrier polymer is a polyethylene glycol (PEG) having an average molecular weight of about 2000 to 12,000 g / mol and a suitable melting point, for example in the range of 30 ° C to 70 ° C. However, PEG, which is the main constituent of these pastilles, has the disadvantage of having a delayed solubility as a polymeric material, which can lead to residues in short washes, low temperature or other unfavorable conditions.

Moreover, PEG is mostly of petrochemical origin. For reasons of sustainability, it may be desirable to use renewable resources. This aspect is all the more important because the carrier material is the main constituent of the perfume pastilles and thus requires large quantities and be introduced into the wastewater.

The object of the present invention is therefore to find a suitable carrier or a suitable carrier material, on the one hand shows a suitable melting range, on the other hand has a faster solubility as a polymeric material, in particular PEG. It is a further object of the present invention to provide fragrance pastilles based on regenerative raw materials. Surprisingly, it has been found that saccharides, in particular mono- and disaccharides, but also oligosaccharides and alditols derived therefrom (sugar alcohols) are suitable as carrier material for the production of fragrance pastilles.

In a first aspect, the present invention is therefore directed to a solid fragrance-containing agent for scenting, characterized in that
it has a carrier and at least one perfume,
wherein the agent contains the at least one fragrance in the form of microcapsules, and
the carrier comprises one or more sugars and / or sugar alcohols selected from simple sugars (monosaccharides), di-sugars (disaccharides), polysaccharides (oligosaccharides), alcohols of these saccharides and mixtures of these.

The objects to be scented are in particular textile fabrics, preferably textiles. "Sugar alcohols", "alcohols of saccharides" and "alditols" are used here synonymously.

In another aspect, the present invention is directed to the use of the solid composition as described herein as a fabric care agent, preferably a fragrance, for perfuming and / or conditioning fabrics.

These and other aspects, features, and advantages of the invention will become apparent to those skilled in the art from a study of the following detailed description and claims. Any feature of one aspect of the invention may be employed in any other aspect of the invention. Further, it is to be understood that the examples contained herein are intended to describe and illustrate the invention, but not to limit it, and in particular that the invention is not limited to these examples.

All percentages are by weight, unless otherwise stated, and are in each case based on the stated composition. Numeric ranges indicated in the format "from x to y" include the stated values x and y. If multiple preferred numeric ranges are specified in this format, it is understood that all ranges resulting from the combination of the various endpoints are also captured.

"At least one" as used herein refers to 1 or more, for example, 1, 2, 3, 4, 5, 6, 7, 8, 9 or more. In particular, this indication refers to the type of agent / compound and not the absolute number of molecules. "At least one perfume" therefore means that at least one kind of perfume is detected, but also may contain 2.3 or more different types of perfume.

"Water-soluble" as used herein means a solubility in water at 20 ° C of at least 1 g / L, preferably at least 10 g / L, more preferably at least 50 g / L.

"Water-dispersible" as used herein means that the corresponding molecule can be dispersed in water at 20 ° C by known methods.

"About" or "approximately" as used herein in connection with a numerical value means the numerical value ± 10%, preferably ± 5%.

"Melt body" as used herein preferably refers to a solid (20 ° C, 1013 mbar) solid that is water-soluble or water-dispersible and substantially non-porous, and is obtainable from the melt dispersions described herein by cooling. For the purposes of the present invention, "melt" does not necessarily mean a melt in the thermodynamic sense. It may also be a slurry of particles, e.g. Sugar crystals in a hot saturated solution. On cooling, sugar then crystallizes out of the solution, which sinters the already existing crystals and leads to solidification, even though none of the ingredients had previously melted. So it is generally a flowable at elevated temperature mass, which goes into a solid state at ambient temperature.

A first subject of the present invention is thus a solid perfume-containing agent which has at least one perfume and at least one carrier. The fragrance is in the form of microcapsules. The carrier comprises one or more sugars and / or sugar alcohols (alditols). The sugar or sugars are selected from simple sugars (monosaccharides), or double sugars (disaccharides) or multiple sugars (oligosaccharides). Preferably, the oligosaccharides comprise sugars having 3 to 20 saccharide units. The carrier may also contain one or more sugar alcohols (alditols) based on the corresponding saccharides, ie monosaccharides, disaccharides, oligosaccharides. Examples of suitable saccharides are glucose, mannose, fructose, lactose, talose, gulose, altrose, allose, idose, ribose, arabinose, xylose, lyxose, mannitose, galactose, sucrose, maltose, maltodextrin and many more. Examples of suitable alditols are sorbitol, xylitol, mannitol, erythritol, glucitol, glucitol, etc.

It is possible according to the invention that the carrier has only one sugar or only one sugar alcohol selected from the above. According to the invention, it is preferred that the carrier has two or more sugars and / or sugar alcohols, ie the carrier may have, for example, 2, 3, 4 or 5 different sugars, in particular 2, 3 or 4, particularly preferably 2 or 3 different sugars. Accordingly, the carrier may also have 2, 3, 4 or 5 different sugar alcohols, in particular 2, 3 or 4, particularly preferably 2 or 3 different sugar alcohols. Also included according to the invention is that the carrier has both one or more sugars and one or more sugar alcohols. In the present invention, for example, a monosaccharide and an alcohol of a monosaccharide are included as well as a monosaccharide and an alcohol of a disaccharide or a monosaccharide and an alcohol of an oligosaccharide. Also, for example, an alcohol of a monosaccharide may be mixed with a disaccharide or an oligosaccharide. Also included according to the invention is, for example, two different sugars mixed with a sugar alcohol or two sugar alcohols with a sugar.

Surprisingly, it has been found that the mixture of two or more sugars and / or sugar alcohols leads to a mixture which has a lower melting point than a sugar or a sugar alcohol alone. In a preferred embodiment, the agent according to the invention thus contains mixtures of non-synthetic carbides and alditols. Preferred are e.g. Mixtures of maltose and mannitol or sucrose and sorbitol.

The o.g. Saccharides usually have a melting point that is too high for processing by pastillation in conjunction with perfume oil, so that it is not possible to process perfume oil with a simple sugar melt. For example, maltose melts at a temperature of 160 ° C - 165 ° C, sucrose at about 180 ° C, with decomposition already occurs. A lowering of the melting point is possible by using a mixture of different saccharides and / or alditols, which in the ideal case can be a eutectic, i. the melting point of the mixture is lower than the melting point of the respective pure substances of the mixture. Such eutectics between sugars are presently particularly preferred.

In a particularly preferred embodiment, the fragrance pastilles according to the invention thus contain a eutectoid mixture of saccharides and / or alditols. Particularly preferred are mixtures of maltose and mannitol and sucrose and sorbitol.

In a further preferred embodiment, the carrier used is a eutectoid mixture of the alditols 6-O-α-D-glucopyranosyl-D-glucitol (GPS, isomaltitol) and 1-O-α-D-glucopyranosyl-D-mannitol (GPM). This mixture is commercially available under the trade name isomalt ^®.

The composition has the carrier according to the invention in particular in a proportion of 50 wt .-% to 95 wt .-%, in particular from 60 wt .-% to 90 wt .-%, particularly preferably from 70 wt .-% to 85 wt. %, based on the total weight of the agent on.

The composition according to the invention also has at least one fragrance in encapsulated form, ie perfume microcapsules. A corresponding microencapsulated perfume may be added as a slurry or in anhydrous form or with water bound by an adsorbent to the carrier and thus incorporated into the agent. The proportion of encapsulated perfume is usually 10 wt .-% to 80 wt .-% based on the weight of the capsule, in particular, the proportion is in the range of 1 wt .-% to 95 wt .-%, in particular of 20 wt. -% to 90 wt .-%, preferably from 40 wt .-% to 85 wt .-%, in particular from 50 wt .-% to 75 wt% or from 60 wt .-% to 70 wt .-%.

The amount of perfume microcapsules in the composition according to the present invention is preferably from 0.1% by weight to 30% by weight or to 25% by weight, preferably 0.5% by weight to 20% by weight or to 15 wt .-%, more preferably 1 wt .-% to 10 wt .-%, in particular from 3 wt .-% to 8 wt .-%, based on the total weight of the composition.

In a further preferred embodiment, the agent according to the invention can also comprise at least one further perfume in addition to the perfume microcapsules. This is in non-encapsulated form and can be, for example, a perfume oil. For the purposes of the present invention, perfume encompasses both the perfume itself and perfume precursors or perfume precursors, both in encapsulated and non-encapsulated form. If the composition according to the invention also contains at least one further perfume in non-encapsulated form (free perfume), the proportion of free perfume is preferably in the range from 0.0% by weight to 25% by weight, in particular 0.1% by weight % to 20% by weight, preferably from 1% to 15% by weight, more preferably from 5% to 10% by weight.

According to the invention, the agent may comprise as perfume in a microcapsule an encapsulated perfume oil, an encapsulated perfume or an encapsulated perfume precursor or mixtures thereof. According to the invention, in addition to the microcapsules, it may also have a perfume or a perfume precursor or a perfume oil which is incorporated in the carrier in an unencapsulated form. As a result, the fragrance experience of the agent according to the invention can be further enhanced and the intensity of the scenting of the object can be improved.

In general, a fragrance is a chemical stimulating the sense of smell. In order to stimulate the sense of smell, the chemical substance should be at least partially redistributable in the air, ie the fragrance should be volatile at 25 ° C, at least to a small extent. If the fragrance is now very volatile, the odor intensity sounds quickly again. At a lower volatility, the smell impression is more sustainable, ie it does not disappear so quickly. In one embodiment, therefore, the perfume has a melting point in the range of -100 ° C to 100 ° C, preferably from -80 ° C to 80 ° C, more preferably from -20 ° C to 50 ° C, especially of 30 ° C to 20 ° C. In a further embodiment, the perfume has a boiling point ranging from 25 ° C to 400 ° C, preferably from 50 ° C to 380 ° C, more preferably from 75 ° C to 350 ° C, especially from 100 ° C to 330 ° C is located.

Overall, a chemical substance should not exceed a certain molecular weight to act as a fragrance, since too high molecular weight, the required volatility can no longer be ensured. In a preferred embodiment, the fragrance has a molecular weight of 40 to 700 g / mol, more preferably 60 to 400 g / mol.

The smell of a fragrance is perceived by most people as pleasant and often corresponds to the smell of, for example, flowers, fruits, spices, bark, resin, leaves, grasses, mosses and roots. Thus, fragrances can also be used to superimpose unpleasant odors or even to provide a non-smelling substance with a desired odor.

The fragrances mentioned can be present in the form of fragrance microcapsules (or also perfume microcapsules) in the composition according to the invention. Likewise, said fragrances may also be present as perfume oil (free fragrance) in a preferred form in addition to the microcapsules.

The microcapsules are microcapsules containing the perfume inside, ie the perfume. The microcapsules may be water-soluble and / or water-insoluble microcapsules. For example, melamine-urea-formaldehyde microcapsules, melamine-formaldehyde microcapsules, urea-formaldehyde microcapsules or starch microcapsules can be used.

The microcapsule in encapsulated form not only the perfume, so the perfume itself have. According to the invention, it can also have a scent precursor. Corresponding precursors or fragrance precursors are those compounds which release the actual fragrance only after chemical conversion / cleavage, typically by the action of light or other ambient conditions, such as pH, temperature, pressure or friction, etc. Such perfume precursors or perfume precursors can be present both in the form of the microcapsule as perfume in the agent according to the invention. Also included in the invention is that the perfume precursor is processed directly in unencapsulated form with the carriers.

In a further preferred embodiment, the agent further comprises water in addition to the carrier and the perfume. The melting point of the sugar / sugar alcohols alone or in mixture and that of the eutectic mixtures may still be too high. A further lowering of the melting point of the carrier is possible by adding small amounts of water. Without being bound by theory, the resulting mixture in this case also does not necessarily have to be a melt in the physical-chemical sense. Likewise, in this case, it may be a slurry of sugar crystals in a hot saturated sugar solution. On cooling, sugar crystallizes out of the solution, which then sinters the already existing crystals. This principle corresponds to the hardening of a frosting in food technology.

The water content is preferably 25 wt .-% or less, based on the total weight of the composition. In particular, the proportion of water in the range of 0.1 wt .-% to 20 wt .-%, preferably 0.5 wt .-% to 15 wt .-%, in particular 1 wt .-% to 10 wt .-% , preferably 3 wt .-% to 8 wt .-%.

It has been shown that the carrier material according to the invention in combination with the stated quantitative ranges of water again experiences a melting point depression. If the agent according to the invention is produced in a melt process, the melting point and thus the processing temperature can be kept low, whereby an incorporated fragrance or perfume precursor does not immediately escape during processing, so that the content of fragrances in the finished agent is greater than in carriers with a higher melting temperature. In addition to water, in a preferred embodiment the agent may also comprise further water-miscible solvents. Examples of suitable solvents are alcohols having 1 to 4 C atoms, in particular methanol, ethanol, isopropanol and tert-butanol, diols having 2 to 4 C atoms, in particular ethylene glycol and propylene glycol, and mixtures thereof and the ethers derivable from the classes of compound mentioned , Further examples of suitable solvents are glycerol, propylene glycol, dipropylene glycol, ethanol, isopropanol, triethylene glycol, short-chain polyethylene glycols, propylene carbonate, MMB etc. If such further solvents are present, their proportion is preferably 25% by weight or less, in particular 0.1% by weight % to 20% by weight, preferably 0.5% to 15% by weight, more preferably from 1% to 10% by weight or from 5% to 8% by weight. -%.

The composition may also contain surfactants, in particular anionic surfactants, preferably alkyl sulfates, in particular C _8-12 alkyl sulfates, and / or of (a) and (c) different water-soluble carrier polymers having a melting point> 30 ° C to 250 ° C, preferably> 40 ° C to 150 ° C, selected from polyalkylene glycols, particularly preferably polyethylene glycol.

The anionic surfactants are preferably alkyl sulfates, especially C _8-12 alkyl sulfates. These are preferably used in amounts of up to 20 wt .-%, particularly preferably up to 10 wt .-%.

In various embodiments, the agent according to the invention may also contain further ingredients that can be used to adjust desired properties of the agent. These substances described below can be used individually or in any combination in the be contained means of the invention. Thus, for example, the agent may further comprise an adsorber material for receiving a fragrance, in particular the non-encapsulated fragrance, inert fillers or auxiliaries, dyes or other ingredients such as, for example, textile or skin-care compounds. These and other optional constituents of the agent according to the invention are explained below.

In preferred embodiments, the agent according to the invention can have, for example, one or more adsorber materials for receiving the fragrance. A corresponding adsorber material can be present in amounts of up to 25% by weight, based on the total weight of the composition. The proportion is preferably in the range from 0.0% by weight to 25% by weight, in particular from 0.5% by weight to 20% by weight, preferably from 1% by weight to 15% by weight. or from 3 wt% to 10 wt%, more preferably from 5 wt% to 8 wt%. Suitable adsorber materials are, for example, porous inorganic substances, such as, for example, silica. Also, organic substances such as crosslinked polymers, eg. B. crosslinked polyvinylpyrrolidone, can be used as adsorber.

In addition, the agent may further comprise fillers or auxiliaries, such as emulsifiers, z. B. Improve the processability in the production or the homogeneity of the distribution of the microcapsules or perfume in the carrier. Suitable fillers and auxiliaries are known to the person skilled in the art.

In various embodiments, the agent as described herein may further comprise at least one textile care compound. In this context, a textile care compound is understood to mean any compound which gives textile fabrics treated therewith a beneficial effect, such as, for example, a textile softening effect, crease resistance or the harmful or negative effects which result during cleaning and / or conditioning and / or or wearing, such as fading, graying, etc., reduced.

The fabric care composition may preferably be made of fabric softening compounds, bleaches, bleach activators, enzymes, silicone oils, anti redeposition agents, optical brighteners, grayness inhibitors, anti-shrinkage agents, wrinkle inhibitors, color transfer inhibitors, antimicrobials, germicides, fungicides, antioxidants, antistatic agents, ironing aids, phobizers and the like Impregnating agents, swelling and slipping agents, UV absorbers and mixtures thereof are selected.

It is particularly preferred that the fabric care compound is a fabric softening compound. It is most preferred that the fabric softening compound is selected from polysiloxanes, fabric softening clays, cationic polymers and mixtures thereof.

The use of polysiloxanes and / or cationic polymers as a textile-care compound in the composition according to the invention is advantageous because they not only have a softening effect, but also enhance the perfume impression on the laundry. The use of softening clays as textile-care compound in the composition according to the invention is also advantageous because they additionally have a water-softening effect and thus, for example, lime deposits on the laundry can be prevented. For optimum performance, it may be preferred that the composition contains a combination of at least two fabric care compounds.

When the composition according to the invention contains such textile-care compounds, it is used in particular as a scenting agent in the main wash of an automatic washing or cleaning process. The agent can be given by the consumer in the desired dosage - in addition to the detergent or cleaning agent - in the corresponding dispenser or directly into the drum of the washing machine. This has the advantage that no additional rinse is necessary and no unsightly deposits occur in the dispenser

Furthermore, such an agent according to the invention can be used in the wash cycle of a laundry cleaning process and thus already transport the textile-care compound and the fragrance directly to the laundry at the beginning of the washing process so as to be able to develop its full potential. Furthermore, the agent according to the invention is simpler and easier to handle than liquid compositions, since no drops remain on the edge of the bottle, which lead to edges on the substrate during subsequent storage of the bottle or to unsightly deposits in the region of the closure. The same applies in the event that some of the product is accidentally spilled during dosing. The spilled amount can also be removed easier and cleaner.

The composition according to the present invention is a solid, particulate agent. The individual particles of the agent can be referred to as body, which are solid at room temperature and temperatures up to 30 ° C, preferably up to 40 ° C.

In a particularly preferred embodiment, the agent according to the invention is a fused body, that is to say the individual particles of the agent may be referred to as fusible bodies. In this case, both the combination of carrier and perfume capsules can be processed to a melt and then spent in the final product form of the agent. According to the invention, however, it is also possible that only the carrier itself is present in the form of a fusible body and is brought into the actual product form, and this product form is subsequently coated with the fragrance microcapsules. The melting temperature of the agent is preferably at least 40 ° C, more preferably at least 45 ° C.

The solid fragrance-containing agent according to the invention is preferably in the form of spherical, hemispherical or lenticular particles. Spherical or hemispherical particles in the sense of the present invention are those particles having a three-dimensional extent, in which at least one surface section of a sphere corresponds to a part of the surface of the medium. For example, a spherical particle may be circular, ellipsoidal, oval, dome-shaped, domed, biconvex, plano-convex, disc-shaped, or discus-shaped, to name just a few examples.

Another object of the present invention is a process for the preparation of the fragrance pastilles according to the invention.

In principle, the agent according to the invention can be prepared by passing the composition of the composition through a nozzle, for example with a slight overpressure.

A preferred method is a Pastillierverfahren in which a melt, which may also be a heated slurry in the context of the present invention, is dropped onto a cooling belt and solidified there with cooling after a certain time. The resulting particles are lenticular or hemispherical. In this case, the melt can also be dripped with pressure on the cooling belt through nozzles. This is particularly useful for higher viscosity melts.

It is possible according to the invention to first prepare from the carrier by means of pastillation a corresponding particle which is then coated with the perfume microcapsules as described above. Likewise, it is possible according to the invention that the agent which comprises both the fragrance microcapsules and the carrier is prepared by means of pastillation.

Another preferred method is extrusion. In this case, the formulations according to the invention are pressed into a strand, for example in an extruder. The shaping takes place by knocking off or cutting off the strand. Optionally, a post-processing of the mold then takes place, for example by spheronization or pressing into another mold. Again, it is possible according to the invention that the carrier is processed alone and the particles thus obtained are then coated with the fragrance microcapsules, or that the agent containing carrier and fragrance microcapsules are processed together in an extruder process.

1. (i) kontinuierliches Erzeugen und Fördern einer Schmelze umfassend den wenigstens einen Träger;
2. (ii) kontinuierliches Zudosieren der Duftstoffmikrokapseln zu der Schmelze;
3. (iii) Mischen der Schmelze und der Duftstoffmikrokapseln; und
4. (iv) Abkühlen und optional Umformen der Mischung um duftstoffhaltige Mittel zu erhalten.

A process for the preparation of agents according to the invention may comprise, for example, the following steps:

1. (i) continuously producing and conveying a melt comprising the at least one carrier;
2. (ii) continuously dosing the fragrance microcapsules into the melt;
3. (iii) mixing the melt and the perfume microcapsules; and
4. (iv) cooling and optionally reforming the mixture to obtain fragrance-containing agents.

In such a process according to the invention, the agents are enamel bodies. The enamel bodies produced in this way can have any desired shape. The shaping takes place in particular in the last step (iv) of the described method.

Solid, particulate forms, such as, for example, essentially spherical, figural, scale, cuboid, cylindrical, conical, spherical cap or lenticular, hemispherical, disc or needle-shaped particles, are preferred for all said production processes. For example, the particles may have a gummibärchenartige, figural design. The maximum extent of the particles in a spatial dimension is preferably from 0.5 to 10 mm, in particular 0.8 to 7 mm and particularly preferably 1 to 3 mm. This means that, for example in the case of spherical particles, the diameter the particle is from 0.5 to 10 mm, in particular 0.8 to 7 mm and particularly preferably 1 to 3 mm. Usually, the weight of the individual particles is from 2 to 150 mg, preferably from 5 to 10 mg.

In various embodiments, the melting in the first step (i) of the described process is carried out by heating to a temperature not more than 20 ° C above the melting point of the carrier. The melting can be carried out using all customary methods and devices known to the person skilled in the art. The melt containing the carrier, for example, continuously generated by the support and optionally further components of the melt body are continuously fed to a corresponding device in which it is heated and the melt thus produced further promoted, for example, is pumped.

In a next step, the fragrance microcapsules and optionally also a dye are then metered continuously to the melt. The dosage of the microcapsules is preferably in the form of a slurry of perfume capsules in a, typically aqueous, solvent. If the agent according to the invention also comprises at least one perfume oil or perfume precursor, it is likewise preferably metered into the melt in the form of a liquid or solution. "Liquid" as used in this context means liquid under the conditions of use, preferably liquid at 20 ° C.

During production, the flow can optionally be measured by measuring the flow rate of the individual metered streams, i. the melt, the perfume stream and possibly other ingredient streams are controlled. This also allows, for example, adjust the proportions of the individual components. Additional ingredients which are used in addition to acting as a carrier material of the sugar mixture according to the invention and the fragrances can be produced either directly together with the sugar mixture as a melt, be dosed together with the fragrances or separately to the melt. In the latter alternative, the dosage can be done before or after dosing the fragrances.

The mixing of the combined metering streams can then be carried out in each case directly after the respective metering or downstream after metering several or all ingredients with suitable mixers, such as conventional static or dynamic mixing units.

After mixing, the melt thus obtained is cooled and optionally fed to the forming, where the melt solidifies and obtains its final shape. Suitable methods for shaping are known to the person skilled in the art. Usual forms have already been described above.

The invention also relates to the use of the solid particulate agent described herein as a fabric care agent, preferably a fragrance, for scenting fabrics.

The composition described herein is particularly suitable for scenting textile fabrics and is brought into contact with the textile fabrics together with a conventional washing or cleaning agent in the (main) wash cycle of a conventional washing and cleaning process.

Compared to known from the prior art agents which have PEG as a carrier material, the inventive composition to a much faster solubility. In addition, mostly sustainable raw materials can be used.
